I've never heard this about the Pens. The secret sauce for the Pens was being a crappy team at the right time,
Boston just manages to find gems left to right in all facets
Drafting guys like Bergeron, Krejci, Marchand, Lucic, Pastrnak, McAvoy and Swayman past the middle of the 1st round and beyond, to signing an undrafted former ECHL goalie Tim Thomas.
Signing a future Norris winner and perennial candidate in Zdeno Chara, to trading a Calder winner Raycroft for a prospect goalie in Tuuka Rask.
More recently, their amateur and pro scouting continues to be one of the best. Zacha, Coyle, Ullmark, Hampus Lindholm were all acquired through trading and free agency.
It remains to be seen, but I think drafting Lohrei (super bullish) and Poitras in the second round of their drafts will pay long term dividends.
